Aadhavan (Suriya) is a professional killer/hit-man who works for Ibrahim Rowther (Sayaji Shinde) who is also his father along with Tharani (Anand Babu)- who is his brother. He is contracted by Abdul Kulkarny (Rahul Dev) to kill prominent Judge Subramaniam (Murali)(who is presently working on child kidnapping and murder cases in the eastern Indian belt for sale of their organs to foreign countries) -but fails to shoot him at the first attempt. He promises to get the judge, angry with himself for having missed such a thing and uses the Judge's innocent servant Bannerjee (Vadivelu) to get into the house as Murugan, Bannerjee's brother in law (He locks up Bannerjee's actual brother in law Murugan in a ship and threatens Bannerjee with his name all the time).Written by i20s9449
